Supreme carbon work.
Enhanced Venturi effects.
The CSL Plenum OE+ variant introduced in 2022, yet a few of us wanted more.
We wanted as close to the CSL prototype.
The Competition Spec aims at achieving this objective with a massively enlarged, fully sealed, complete carbon intake system running exclusively on AlphaN.
I've built upon the original Special Series to dive into the development, test fitment, performance testing and impressions of the Competition variant.

No! However, Sal and I are looking to see if a tune can be optimized for the larger air volume. TBD.
I first want to test these before making them available.
Hear the OE+ variant
The complete carbon intake runs using Alpha N as the engine mapping protocol.
The larger inlets will not have MAF bungs to optimize for space.
A new pair of Intake Air Temperature sensors will be required (like pictured).
I documented in vast details the installation process of the OE+ plenum. I will further document the Competiton Spec specifics.
If your mechanic thinks he's smart and skips this, don't pay the bill.
Overall the car feels more responsive, pulls like a train! The sound is very S54 CSL-esque: addicting, intoxicating - all apply.
InfinityDesign's unique product design and engineering is crafted by the grand-daddy of the most popular S85 products and tuners to hundreds of S85s: Salman.
As a former Evolve co-owner, he headed engineering & development for all products.
He notably signed off on numerous popular V10 products: e-tronic exhaust systems, headers, cat deletes, carbon intakes along with the V8 supercharger kits & tuning maps during the 2000s until he exited the company in 2015.
Been there, done that.
